THE PIVOT ENGINE The Pivot Engine will "pivot" on any matrix element. Thus, using row operations, the chosen pivot becomes "1", and all other entries in the pivot's column become ZERO. Applications include: Solving systems of equations Finding inverses of matrices Linear programming with Simplex Method

CHOOSE MATRIX DIMENSIONS Choose below the dimensions of the matrix you are working with. Count all rows and columns, on both sides of any partition bars. 2x3 2x4 2x5 2x6     3x3 3x4 3x5 3x6 3x7     4x4 4x5 4x6 4x7 4x8

NetScape 3.0+ or Internet Explorer 4.0+ is required for these pages to work properly. For larger matrices, the page loads more slowly, but once it is loaded, it works fast. UWW Math Prof Bennette Harris has written a Windows-based program (size = 315 KB) which pivots larger matrices. To use this program, you must copy it to your PC. DOWNLOAD WINDOWS PIVOTING PROGRAM?
